Slot a1 problem

[Terminal]

Our company (Shahr Electronic) has been assembling computers for over 10 years. Recently, one of our customers encountered an issue after about a year of use. The problem started with continuous BSODs (Blue Screen of Death), eventually leading to prolonged boot times.

Through our investigations, we determined that all components, except for the CPU, are in perfect condition. The main issue is that the CPU exhibits the same problem on every motherboard: it doesn't boot on slots A2 and A1, and the motherboard gets stuck on DRAM lighting. As other individuals have also observed this problem, it seems to be related to the IMC (Integrated Memory Controller) of the CPU.

The complete system specifications are as follows:

Asus Rog Strix Z790 F Gaming Wifi DDR5
Intel Core i9-13900K
ASUS ROG RYUJIN III 360 Noctua
Corsair VENGEANCE 64GB (32GBx2) 5200MHz CL40 DDR5 (X2)
SAMSUNG 980 Pro 1TB (X2)
ASUS RTX 4090 ROG STRIX OC
ASUS ROG STRIX 1200W Gold Aura Edition
ASUS TUF Gaming GT502 Black Mid Tower Case
DeepCool CF120 Plus (X2)
The motherboard BIOS is up to date, BIOS settings are at default, and XMP is disabled (we have a total of 128GB RAM).

The purpose of this message is to seek a suitable solution and to get the Blue Team's opinion on this matter. We eagerly await your response.

Here’s an example of a similar issue encountered by an internet user:

That means we have to trash the cpu?
